Benefits of technology
The present invention is a three-dimensional additive manufacturing device, system, and method that allows for the melting of multiple types of metal powder to create a shaped object. The device includes a stage, powder supply unit, beam irradiation portion, storage portion, and control portion. The powder supply unit spreads the metal powder on the stage while the beam irradiation portion uses a charged particle beam to melt the metal powder. The control portion controls the beam irradiation portion to emit the charged particle beam with an output based on the type of metal powder and the coordinate position it is directed to. The invention allows for the creation of shaped objects made from multiple types of metal powder.
Problems solved by technology
Therefore, with the prior-art three-dimensional additive manufacturing device, a shaped object cannot be constructed by using a plurality of types of metal powder made of metal powder.

Abstract
A three-dimensional additive manufacturing device which can construct a shaped object by using a plurality of types of metal powder, a three-dimensional additive manufacturing system, and a three-dimensional additive manufacturing method are provided.A three-dimensional additive manufacturing device 100 includes a stage 4, a beam irradiation portion 8, a storage portion, 42, a control portion 40, and a powder supply unit. The powder supply unit has a plurality of powder accommodating portions accommodating a plurality of types of metal powder and discharging the plurality of types of Metal powder to the stage 4 and a holding mechanism for holding a plurality of powder accommodating portions and spreads the plurality of types of metal powder on the stage 4. The control portion 40 controls the powder supply unit so as to spread the plurality of types of metal powder on the stage 4 and controls the beam irradiation portion 8 so as to emit a charged particle beam with an output according to each metal powder on the basis of beam control data 64 read out of the storage portion 42.
Description
CROSS REFERENCES TO RELATED APPLICATIONSBackground of the Invention[0001]1. Field of the Invention[0002]The present invention relates to a three-dimensional additive manufacturing device which irradiates a plurality of types of powder sample made of metal powder with an electron beam, for example, to perform additive manufacturing, a three-dimensional additive manufacturing system, and a three-dimensional additive manufacturing method.[0003]2. Description of the Related Art[0004]An optical shaping device is widely known which shapes a three-dimensional object by irradiating a powder layer made of resin powder spread on a stage with a laser beam so as to melt the resin powder and by laminating layers in which the resin powder is solidified. In recent years, a three-dimensional additive manufacturing device is used which shapes a three-dimensional object by performing additive manufacturing of laminating layers in which the powder samples are molten and solidified by irradiating a spe...
